Pick random instance

I want the system to pick a random instance of ball (there are three balls by the way) and destroy it without harming the others, how? Ashley?

Just create a new condition or event System->Pick Random Instance.

Yes, Zephlon, i did but when you type

SystempickrandomBallinstance        Ball Destroy

It destroys all of the Balls! I'm not sure how to fix this. I guess I should've beeen more specific...

can you provide your capx ?

Here's an example:

If "Pick random instance" is the only condition you have, it will just keep picking instances and destroy them one after the other, so you'll probably need another condition i.e. "Trigger once while true".

Don't worry, I figured it out (with your help of course)

How did you get it to work? I'm trying something similar and it keeps selecting all the objects. I have...

On created

> System Pick a random Object instance

    > Trigger Once > Object Set Opacity to 10

Doesn't work. I tried putting the Trigger Once everywhere, inside the parent condition any outside and all over the place to no avail.

Trigger once while true has to be tied to something. What is making it run? An object being created? Well then, anytime an object is created, it will be destroyed, it's opacity will be set, etc.

Oh hey I figured it out too. I'll post my solution though for anyone that searches for this exact same issue:

1. create a global variable (gvar) you're going to count up

Object on created > Add 1 to gvar

System gvar >= total number of expected objects

-->System pick a random Object instance + Trigger Once > Object (destroy, or do whatever to it)

In my case it looks like this:

TiAm: Yeah that was exactly the issue. I should go to sleep, brain not working at full capacity :<

Glad you figured it out. Thanks for posting your solution; no matter how trivial/simple it may seem to you now, it really helps others who might come across your post later. <img src="smileys/smiley20.gif" border="0" align="middle" />
